Gas Questions and Answers (Q&A)

The answer to this question is C. To understand how this question, you need to know how to solve this. 1 atm is equal to 760mm Hg. This means 735x 1/760=0.967 atm. It would be easy to solve this already as long as you know the right equation to use. Measuring atmospheric pressure is essential because this will have some effects on water chemistry as well as the different weather conditions that may be experienced. Various gases may dissolve more in higher atmospheric pressures as compared to low atmospheric pressures. Do remember that air temperature usually decreases in more upper atmospheres.

In fact we do breathe in other gases besides oxygen but we breathe them out again. For instance, nitrogen which is present in the air around us is inert. This means it will not combine or change anything it comes into contact with. You will be breathing in nitrogen (and other things) with the oxygen but the body needs oxygen.

It does not need nitrogen so the nitrogen leaves the body without altering it in any way. By contrast, oxygen is used by the body first entering the lungs then oxygenating our haemoglobin. It is this enrichment of our blood circulating that enables our bodily system to function properly. We do use nitrogen but not through breathing it. We absorb it through our skin, a different process.

Tear gas is a chemical compound, which is often used as a weapon. Unlike how the name suggests, tear gas is not a gas. Instead, it is a powder, or it can sometimes be drops of liquid. Similar to pepper spray, the chemicals found in the power cause pain to the eyes. The chemicals found in tear gas are CS gas and phenacyl chloride (CN).

Tear gas can cause temporary blindness, which can last up to 45 minutes. Like pepper spray, tear gas is commonly used by police to control crowds in settings like concerts or protests. It can sometimes be used in war to hinder the opposing side.

Matter can be in the form of a liquid, solid or gas. Each of these types of matter have certain specific properties that identify it as a liquid, solid or gas. Gases have specific properties including having a low density.

The molecules in a gas are scattered about and are not tight or compact. Therefore, the gas is not dense. Also, the gas does not have a specific shape. Since the molecules are not compact, it would not form a shape or have a certain type of volume.

Gases also allow it to be compressible and expandable. Since there is low dense, the gas can be compressed. Diffusion is also something that can happen to a gas due to its configuration. There is high pressure in a gas.

Both Regular gas and premium gas are fuels for car engines. The two are similar in terms of their usefulness and there are also differences between the two. Regular gas is the most common fuel for cars because it contains no lead compounds which makes it less hazardous to human health. It is gotten from crude oil. It has an octane rating of 87, this refers to its ability to resist improper combustion in the engine.


Premium gas is also a product of crude oil. It performs relatively functions similar to premium gas. But it has a higher price than regular gas. The octane rating is about 90 and more, this is where it differs from regular gas. The octane rating of 90 in premium gasoline means that it is able to withstand knocking just a little more than regular gas. Because of its high octane ratings it causes less pollution, it will leave your engine very clean and that's why most people go for it.

There are a lot of differences between Propane and Ammonia gas. Although, there is presence of hydrogen in the two gases which is one of the similarities between them apart from the fact that they are both gases. Ammonia is an inorganic compound and gas specifically and has the molecular formula of NH3. Nitrogen and Hydrogen are the two constituents of the compound.


It is highly soluble in water and it is lighter than air. The gas can be produced in the laboratory and is gas available in the atmosphere because it is also produced from animal and vegetable decays. While Propane is an organic compound and is a member of alkane family. Carbon and hydrogen are two constituents of the compound with the molecular formula of C3H8. It is a natural gas gotten as petroleum bye product and can be used as fuel for engines, cooking stoves etc.

Gas molecules inside a volume (e.g. a balloon) are constantly moving around freely. During this molecular motion they frequently collide with each other and with the surface of any enclosure there may be (in a small balloon that would be many thousands of billions of collisions each second).

In a science experiment, you have three flasks that are filled with different gases in them. If you have some form of nitrous oxide in them, they will have the same kinetic energy. However, there are different amounts of kinetic energy in gases.

Kinetic energy is the energy that most people think of when they think of power. It is the energy that occurs when it is in motion. Gas is free-flowing just like a liquid. This means that the molecules are moving about. Even though NO, NO2, and N2O are different gases, they all have the same amount of movement. NO2 is called nitrogen dioxide based on the number of molecules it has in it. N2o is nitrous oxide. NO is nitric oxide.

The correct answer to this question is E, None. Gases in chemistry are one of the three states of matter that have no defined volume or shape. Each gas has a standout behavioral pattern. This behavior can depend on many variables including temperature, size, and pressure. Though their actions are different, all gases act the same.

Particles are what makeup gas. These particles can be various things including molecules and atoms. There are multiple types of gases, including elemental gases, which are elements that become gases at standard pressure and temperature. Examples of elemental glasses include hydrogen, xenon, and krypton.
